What are the coordinates of 2x-4y=6 and 3x+y=-5 ?

The coordinates are x = -1 and y = -2.

Step-by-step explanation:

Given:

Equations are 2x-4y=6 and 3x+y=-5.

Now, to find the coordinates.

...........(1)

...........(2)

So, first we solve the equation 1 to get the value of .

Subtracting both sides by we get:

Dividing both sides by 2 we get:

Now, we put the value of in equation 2 to get .

On solving the whole equation we get :

And, now putting the value of in equation (1) we get :

on solving we get:

Therefore, the coordinates are x=-1 and y=-2.

answer: (1,3) and (-2,0) i think.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
